Prospective comparison of capillary and venous brain biomarker S100B : Capillary samples have large inter-sample variation and poor correlation with venous samples

Background: Guidelines for the emergency management of mild traumatic brain injury have been used for over a decade and are considered safe. However, they recommend computerized tomography for at least half of these patients. The Scandinavian Neurotrauma Committee guideline uses serum S100B protein level to rule out intracranial hemorrhage. Analysis of capillary serum S100B protein level has not y

Environmental surveillance of polioviruses in armenia, Colombia before trivalent oral polio vaccine cessation

Although acute flaccid paralysis (AFP) surveillance is the “gold standard” for detecting cases of polio, environmental surveillance can provide supplementary information in the absence of paralytic poliomyelitis cases. This study aimed to detect the introduction and/or circulation of wild poliovirus or vaccine-derived polioviruses (VDPV) in wastewater, covering a significant population of Armenia,

Coherent Bragg imaging of 60 nm Au nanoparticles under electrochemical control at the NanoMAX beamline

Nanoparticles are essential electrocatalysts in chemical production, water treatment and energy conversion, but engineering efficient and specific catalysts requires understanding complex structure-reactivity relations. Recent experiments have shown that Bragg coherent diffraction imaging might be a powerful tool in this regard. The technique provides three-dimensional lattice strain fields from w

Investigating the link between transport sustainability and the representation of women in Swedish local committees

There are large discrepancies in the transport sector along gender lines in travel patterns and means of transportation used, but also in attitudes and norms among citizens, planners and decision-makers, with women generally more positive towards measures involving the lowering CO2 emissions. At the same time, the number of women involved in transport-related decisions is low. This is a problem fo

Sunbed Use Increases Cutaneous Squamous Cell Carcinoma Risk in Women : A Large-scale, Prospective Study in Sweden

The incidence of cutaneous squamous cell carcinoma has increased rapidly in Sweden in the past decades. Here, we present a prospective study of the Melanoma in Southern Sweden (MISS)-cohort, with 29,460 participating women in southern Sweden that investigates the risk factors for cutaneous squamous cell carcinoma. Data on the host and skin cancer risk factors were collected through questionnaires

Recognition of dementia with Lewy bodies. Prevalence of core signs, medical treatments and survival in Swedish nursing homes and short-term homes.

Enligt statistiska prognoser beräknas Sveriges och världens population av äldre ökakraftigt de nästkommande åren. Kognitiva sjukdomar (demens) är åldersrelaterade och2015 estimerades prevalensen i världen till 47 miljoner människor.I Sverige idag finns det 160000 människor med en demensdiagnos, med en årlig ökningmed 25000 nya insjuknande. Demens, ett paraplybegrepp med flera olika sjukdomar,beståDementia with Lewy bodies (DLB) is an underdiagnosed neurocognitive disorder thatincludes several complex neurological and psychological signs, which are challenging toclinical diagnostics. The recognition of this neurocognitive disorder should beimproved because people with DLB exhibit a good treatment response to anti-dementiamedications but experience severe adverse events if treated with anti-

Role of cgrp in migraine

Migraine is a common neurological disorder that afflicts up to 15% of the adult population in most countries, with predominance in females. It is characterized by episodic, often disabling headache, photophobia and phonophobia, autonomic symptoms (nausea and vomiting), and in a subgroup an aura in the beginning of the attack. Although still debated, many researchers consider migraine to be a disor

Imprint of the galactic acceleration scale on globular cluster systems

We report that the density profiles of globular cluster (GC) systems in a sample of 17 early-Type galaxies (ETGs) show breaks at the radii where the gravitational acceleration exerted by the stars equals the galactic acceleration scale a0 known from the radial acceleration relation or the modified Newtonian dynamics (MOND). The match with the other characteristic radii in the galaxy is not that cl

An exploratory study of verbal interaction between children with different profiles of DLD and their classroom teachers in educational dialogues

Children with a history of developmental language disorder (DLD) entering school are a challenge for classroom teachers. Teachers are often not very familiar with DLD, and language difficulties in school age children are often not obvious in context-supported everyday language. However, their language is still vulnerable. The teachers’ way of talking with four children with DLD, two with predomina

Differential fitness effects of moonlight on plumage colour morphs in barn owls

The Moon cycle exposes nocturnal life to variation in environmental light. However, whether moonlight shapes the fitness of nocturnal species with distinct colour variants remains unknown. Combining data from long-term monitoring, high-resolution global positioning system tracking and experiments using prey, we show that barn owls (Tyto alba) with distinct plumage colourations are differently affe

Two-dimensional graphene paper supported flexible enzymatic fuel cells

Application of enzymatic biofuel cells (EBFCs) in wearable or implantable biomedical devices requires flexible and biocompatible electrode materials. To this end, freestanding and low-cost graphene paper is emerging among the most promising support materials. In this work, we have exploited the potential of using graphene paper with a two-dimensional active surface (2D-GP) as a carrier for enzyme

Gender differences in autobiographical memory : females latently express communality more than do males

Gender differences have been found in several aspects of autobiographical memory (i.e. personally experienced events). For example, previous studies have shown that females’ autobiographical memories contain more communal and emotional expressions than do males. However, an important question concerns whether these differences can be observed both in the manifest content (i.e. what is actually sai

Cardiovascular risk in non-alcoholic fatty liver disease : Mechanisms and therapeutic implications

New evidence suggests that non-alcoholic fatty liver disease (NAFLD) has a strong multifaceted relationship with diabetes and metabolic syndrome, and is associated with increased risk of cardiovascular events, regardless of traditional risk factors, such as hypertension, diabetes, dyslipidemia, and obesity. Given the pandemic-level rise of NAFLD—in parallel with the increasing prevalence of obesit

Single-Molecule Detection with Lightguiding Nanowires : Determination of Protein Concentration and Diffusivity in Supported Lipid Bilayers

Determining the surface concentration and diffusivity of cell-membrane-bound molecules is central to the understanding of numerous important biochemical processes taking place at cell membranes. Here we use the high aspect ratio and lightguiding properties of semiconductor nanowires (NWs) to detect the presence of single freely diffusing proteins bound to a lipid bilayer covering the NW surface. S

Vertical III-V Nanowire MOSFETs

Vertical III-V nanowire MOSFETs are interesting candidates for future digital and analog applications. High electron velocity III-V materials allow fabrication of low power and high frequency MOSFETs. Vertical vapor-liquid-solid growth enables fabrication of axial and radial heterostructure nanowires. This enables fabrication of novel structures where the band-gap can be engineered in the electron

Macroevolutionary origin and adaptive function of a polymorphic female signal involved in sexual conflict

Intersexual signals that reveal developmental or mating status in females have evolved repeatedly in many animal lineages. Such signals have functions in sexual conflict over mating and can therefore influence sexually antagonistic coevolution. However, we know little about how female signal development modifies male mating harassment and thereby sexual conflict. Here, we combine phylogenetic comp
